節點json請求堆棧

Question

大家好，我知道我的問題很容易購買我是新的使用json。

var mysql = require('mysql'); 
function myCon(sql){ 

var con = mysql.createConnection({ 
     host: "127.0.0.1", 
     port: "3306", 
     user: "root", 
     password: "xxxxxx", 
     database: "myDataBase", 
    }); 
    // here i'm passing sql query as var sql 
con.query(sql, function(err, rows) { 
    if (err) { throw err } 
    else { 
      console.log(rows); 
      // here I want my response to be json response eg { key:value} 
     } 
}) 
con.end(); 
} 

module.exports.con = myCon; 

結果是

[ RowDataPacket { countryId: 1, countryName: 'N/A' }, 
    RowDataPacket { countryId: 2, countryName: 'UK' }, 
    RowDataPacket { countryId: 3, countryName: 'USA' }, 
    RowDataPacket { countryId: 4, countryName: 'UAE' } ] 

我想要的響應是作爲

{ countryId: 1, countryName: 'N/A' }, 
    { countryId: 2, countryName: 'UK' }, 
    { countryId: 3, countryName: 'USA' }, 
    { countryId: 4, countryName: 'UAE' } 

與出RowDataPacket 並將其重新發送到EJS視圖

Answer 1

[ 
    RowDataPacket { countryId: 1, countryName: 'N/A' }, 
    RowDataPacket { countryId: 2, countryName: 'UK' }, 
    RowDataPacket { countryId: 3, countryName: 'USA' }, 
    RowDataPacket { countryId: 4, countryName: 'UAE' } 
] 

這是控制檯如何顯示結果，因爲從MySQL返回的數據類型爲RowDataPacket，但實際得到的只是您想要的對象，您不必真的做任何事情。

如果你真的想擺脫的類型，你可以做

con.query(sql, function(err, rows) { 
    if (err) { 
     throw err 
    } else { 
     var str = JSON.stringify(rows); 
     rows = JSON.parse(str); 

     console.log(rows); 
    } 
});
